Physical activity can alleviate symptoms of anxiety and depression by promoting the release of endorphins and other neurotransmitters that improve mood. Regular exercise influences brain chemistry, increasing levels of serotonin and norepinephrine, which are linked to happiness and reduced anxiety. Exercise also enhances sleep quality, promotes relaxation, and can serve as a healthy coping mechanism for stress. By engaging in physical activity, individuals can create a sense of accomplishment, enhance self-esteem, and improve overall emotional well-being.
